To all whom it may concern:

.Be it known that I, VICTOR D. LESPINASSE,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful attachingsaid testicle to the back into a cord which can beeasily cut and the testicle removed.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Fig. 1 is a view in perspective of the instrument being manipulated with atestiole attached thereto; and Fig. 2 is a View in perspective of the instrument alone.

Similar letters of reference refer to similar parts throughout the several, views.

-The instrument comprises a handle (a, which may be made of metal or other suitable material, at one end of which a loop or eye Z) is formed, of suitable size to pass over the testicle of the bird. I have shown this eye I) as formed by making one end of the instrument of twisted wires 0 andd, made onto or attached to the handle a, which wires '0 and (Z are spread apart to form said Extending from the eye Z) and 7 vessels attached to the testicle through itand hold the testicle firmly while it is bev ingtwisted. This slot 6 may be conveniently formed as illustrated, i. e., by having it formed of the same wires 0 and d, which are attached to the handle a and spread to form the eye I).

To assist in the manipulation of the instrument I have found it better to have the plane of thepart bearing the slot 6 formed at an angle,preferably a right angle, to the plane of the partbearing the eye 6, but this is notessential.

The method of operation of the instrument is as follows: The bird is bound and held, an incision made between its last two ribs, the edges of the cut spread and access to the testicles obtained in the customary manner.

' The testicle being nowexgosed, my instru- I ment is held by the handle, as illustrated in Fig. 1,.it beingheld lightlysas a pen would be held. It isput down into the'cut, .preferably being pointed toward the birds head.

The testicle f is then threaded through the I eye 6 of the instrument from the head of thebird toward the tail. N0 force is necessary to do this If any force appears necessary the testicle is not going on properly and the direction of the instrument should be changed. The testicle can be threaded on the instrument from the tail to the head if preferred. 7

After the testicle has gone through the eye 6 of the instrument the instrument is still drawn so that the blood vessels attached to the testicle enter the slot 6 and the testicle is firmly fixed on-the upper edge of said slot, as shown in Fig. 1 ment is continuously pulled toward the operator and continually twisted, this gradually bringing the testicle up out of the cut and twisting the blood vessels 9 attaching it to the back into a cord which can now be cut with scissors or knife in the usual way. When this has been done the cut is closed as is usual-in such operations.

My invention has particular reference to the caponizing of chickens, but the instru .ment can, of course, be used in any other instance where removal of the testicles from any bird is desired.

Having now described my invention, what I claim as new and desire to secure by Let ters Patent of the United States. is

1. An instrument'for seizing and raising Then the inst-ruv the testicle of a bird, comprising a handle and a member having an eye and a slot communicating with the said eye, substantially as described.

2. An instrument for seizing and raising the testicle of a bird, comprising a handle and a member having an eye and a slot portion of said member bearing said eye,

substantially as described.

closed at one end and communicating at the 4- In an instrument for seizing and raisremote from said handle, and a pair of sub-- stantially parallel portions in which said converging portions respectively terminate,

. said parallel portions being joined together at their ends remote from said converging portions.

6. In an instrument for seizing and raisingthe testicle of a bird, a handle, a pair of spaced members having converging portions remote from said handle, and a pair of sub stantially parallel portions in which said 20 converging portions respectively terminate, said parallel portions extending at an angle to the plane of said converging portions and being joined together at their ends remote from said converging portions.
